摘要

对某试验用齿轮箱进行了模态贡献量与面板声学贡献量分析，确定齿轮箱运行过程中箱体振动主要贡献模态和噪声辐射面板；结合振速法原理，对箱体表面振动与辐射噪声的关系进行了分析，实现基于有限元方法对箱体进行稳态振动响应求解与主要面板辐射声功率级的计算；将主要贡献模态固有频率和面板辐射声功率级作为目标函数，编制APDL的优化求解程序对齿轮箱箱体实现了减振降噪优化，得到了箱体各壁面的最优壁厚组合.结果表明，该方法具有很好的减振降噪效果，为齿轮箱的优化设计提供了借鉴意义.

Abstract

The mode contribution and the panel acoustic contribution analysis of an experimental gearbox are discussed in this research. The main contribution to the modal and the main panel of the noise radiation are determined. Then, the relationship between the surface vibration and radiated noise of the gearbox is investigated according to the finite element method combined with the vibration velocity method. On the basis of above investigation, the radiated sound power level of the main panels of the gearbox is calculated. This parameter and the natural frequency of the main contribution mode could be an objective function of the gearbox vibration and noise reduction. Optimization program which is wrote by APDL. According to the simulation analysis, an optimal thickness for the gearbox can be obtained. The results of this paper show that this method is effective for noise and vibration reduction. It is helpful for the optimization design of the gearbox.
